"Give me that giant banana, I will take care of it for you. Come on, get going, you can't rest yet!"
Cranky Kong

A Giant Banana is a large banana won as a prize, or trophy of sorts by defeating a boss in the original Donkey Kong Country. They would appear at the end of every boss battle and be presumably added to the hoard, but oddly the game does not show the hoard gaining any bananas until King K. Rool is beaten. According to the Game Boy Advance remake of the game, Cranky Kong takes care of the giant bananas. Also, a Giant Banana would appear near his cabin when visited.

These bananas have made a few Easter-egg appearances, such as in the background of The Flying Krock and Swanky's Bonus Bonanza, but have not appeared in any other Donkey Kong Country game since. In its sequels, the Giant Bananas were replaced with prize coins.

It's worth noting that in the Super Nintendo Entertainment System version of the game, the giant bananas had Nintendo logos on them, but were removed in remakes.
